the specific heat of aluminum is 0.214 cal/g degrees C. calculate the heat necessary to raise the temperature of 55.5g of aluminum from 23 to 48.6 degrees C

q = mass x specific heat x (Tfinal-Tinitial)

To calculate the heat necessary to raise the temperature of a substance, we can use the formula:

Q = m * c * ΔT

Where:
Q is the heat (in calories)
m is the mass of the substance (in grams)
c is the specific heat capacity of the substance (in cal/g degrees C)
ΔT is the change in temperature (in degrees C)

In this case, we need to find the heat necessary to raise the temperature of 55.5g of aluminum from 23 to 48.6 degrees C. Plugging the values into the formula, we get:

Q = 55.5g * 0.214 cal/g degrees C * (48.6 degrees C - 23 degrees C)

Simplifying the equation:

Q = 55.5g * 0.214 cal/g degrees C * 25.6 degrees C

Q = 302.712 cal

Therefore, the heat necessary to raise the temperature of 55.5g of aluminum from 23 to 48.6 degrees C is 302.712 calories.
